GEORGE J. HILL, OF BUFFALO, NEW YORK, ASSIGNOR TO SANFORD, HAR- ROUN & GO.

HAND-STAM P.

Specification forming part of Letters Patent No. 38,535, dated May l2, 1863.

To all whom tt may concern Be it known that I, GEORGE J. HILL, of the city of Buffalo, and State of New York, assignor to SANFORD, HAREOUN & Go., of the city of Buffalo aforesaid, printers, have invented certain new and useful improvements in machine for printing or vsta-mping names, dates, business-cards, circulars, trade-marks, &c., upon letters, envelopes, tickets, bills, packages, and the like, in a cheap, convenient, and expeditious manner, which improved machine is commonly known as a Dating or Stamping Machine;77 and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Fig. I is avertical section, and Fig. II a plan.

The nature of my invention consists in combining with a bed containing the form of types or plate from which the impression is to be taken, and a stamping-platen with which to give the impression, a ribbon or strip, prepared with chemical ink and capable of being moved over the face of the type or plate by spools orequivalent means, whereby I am enabled to print a succession of impressions without the necessity of an inking apparatus.

Letters of like name and kind refer to like parts in each of the figures.

A represents the main supporting framework of the machine, made of cast-iron, and B is a bent beam, which rises therefrom and is for the purpose of supporting and guiding the platen C in a vertical position and movement over the type-form D.

E is a rod, which connects with the platen C', and works through a slot or hole in the overhanging end of the bent beam, as shown in the drawings. This rod has an enlarged head, as shown at E', upon which the operator strikes a quick blow with his hand, thereby forcing the platen down upon the thing to be stamped 0r printed, which is laid upon the face of the type. A coiled spring, F, surrounds the rod E, between its enlarged head and bent beam, i'or the purpose of lifting the platen from the type as soon as the impression is made.

Gr represents a type-bed, made of brass or other suitable metal, and tted into the main frame-work. This type-bed receives and holds the type-form or stereotype-plate which contains the subject-matter to be stamped or printed. The type-form I) may be put in or removed from its place in or on the bed at pleasure. It is held in its place by means of the spring J. All of these parts now referred to are similar in construction and operation to like parts described iu a patent granted to me on the 26th lday of June, 1860, for dating-machine, No. 28,861, and to which reference may be had.

K represents a spool or drum placed in rear of and a little lower than the typeform, and K the shaft upon which it turns, and L is a milled wheel on the end of the shaft for turning the same.

M is a spool or drum placed forward of and a little lower than the type-form,and M the shaft upon which it turns, and N is a milled wheel upon the end of the shaft for turning the same.

E is a belt or strip of silk ribbon, or other suitable material, twelve yards (more or less) in length. This ribbon is thoroughly saturated with chemically-prepared ink and rst wound upon the rear spool, K. The outer end of this ribbon is then led off and carried over the face of the type and type-bed and connected to the forward spool, M, so that it may be slowly wound or run off from the rear to the forward spool, and th en again rewound onto the rear spool, and so run from one to the other as may be required in the practica-l operations of the machine. Springs S and T are caused to press upon the rim of each spool or drum, so as to create sufficient friction in the movements of the spools to keep the ribbon smooth over the faceof the type. The spools may be turned slightly in opposite directions, for the purpose of straining the ribbon over the face of the type.

I have devised a peculiar quality of ink for saturating the ribbon, which is compounded as follows-to wit: Half pound of lamp-black, one pint glycerine, and half an ounce of castile soap. These ingredients, in the proportions named, are to be thoroughly ground and mixed together, and the ribbon or strip thoroughly saturated therewith before it is wound upon the spools. The ribbon will hold ink enough to make twenty-tive or more distinct and successive impressions without change of position upon the type. lf the ribbon is then moved,

by means of the spools and milled wheels, as aforesaid, so as to bring a new bearing upon the face of the type, twenty-tive more distinct and successive impressions may be made, and so 011 until the entire length and surface of the ribbon has been subjected to such impressions upon the face of the type. Thus, nine hundred (more or less) impressions may be obtained on each yard of ribbon in once passing over the face of the type, and such is. the effect of Winding the ribbon on the spools in successive coils upon itself, that the ink` remaining in the ribbon Will be evenlyY distributed over and through all parts of the ribbon, those parts which had become exhausted by immediate con tact With the vface of the type bein g resupplied from other portions not immediately in contact, and thus an even distribution ot' the ink through the entire body ot the ribbon is obtained and continued until the ink is Wholly exhausted from the ribbon, and consequently the ribbon may be run from one spool to the other three times in succession and give distinct impressions each time,

as aforesaid. The ribbon may then be resaturated with ink and used over again, or a ner ribbon or strip mayr be supplied.

Although I have hereinabove described the kind or quality of chemical ink with which the ribbon may be saturated, l do not Wish to be understood as limiting my claim of invention to the use of an ink so prepared, as other preparations may be substituted therefor.

What I claim as my invention, and desire to secure by Letters Patent, is-

'.lhe combination of a belt or strip of ink- .prepared ribbon With a bed for holding the form of types or plates, anda stamping-platen, the parts being so arranged that the ribbon may be run from spool to spool over the face of the type and a succession of impressions printed without an inking apparatus, for the purposes and substantially as described.
